Unlike movie quote databases that just let you search, LineRelay chains 34,908 classic movie quotes by meaning. Drop in one line and watch it relay to a quote from a different film that shares its soul, not its words. What makes it different: • Semantic chaining via pgvector — meaning over keywords • Hybrid search picks surprising next quotes • Open source: FastAPI + Next.js + Postgres + Redis For cinephiles and devs curious about vector search in the wild.
